Answer:
S(x) = x² + 390224/x
Step-by-step explanation:
Volume of the open box = V = 97556 cm³
Material needed:
Let´s call x the side of the square base then the area of the base is
A(b) = x²
For the sides of the box, we have 4 sides each one with area of x*h
where h is the height of the box
The volume of the box V(b) = 97556 = x²*h then h = 97556/x²
S(x,h) = x² + 4*x*h*
The surface area of the box as function of x is:
S(x) = x² + 4*x*97556/x²
S(x) = x² + 390224/x

Step-by-step explanation:
Percent is pars out of 100
40%=40/100=4/10=0.4
'of' means multiply
0.4 times something=56
divide both sides by 0.4
something=140
th enumber is 140
Multiply his AGI by 7.5% to find the amount medical needs to meet before deducting:
46,000 x 0.075 = $3,450
He can deduct any amount over $3450.
Subtract that from his medical total to find the amount he can deduct:
5800 - 3450 = 2350
He can deduct $2,350.
